YouTube interview (Ben Greenfield with Megan Lindquist) about AHCC, a cultured mycelial mushroom product originating in Japan. The conversation covers AHCC’s origin (developed 1986), manufacturing (single patented source in Sapporo, Japan; cultured liquid mycelia), proposed mechanisms (NK-cell activation/immune modulation, antioxidant effects including glutathione-related activity, anti-inflammatory effects — lowered CRP, and improved stress response/ resilience), safety profile, dosing guidance, and several human studies. Notable study claims cited in the interview: an in-hospital study of 195 late‑stage cancer patients given ~6 g/day AHCC for six months (reported 114/195 with ≥50% tumor-size reduction within four weeks; 17 reported complete tumor disappearance within four weeks); a 2022 phase‑2 double‑blind placebo‑controlled trial of 50 participants with persistent high‑risk HPV using 3 g/day AHCC for six months (63.6% clearance in treatment group; placebo group later crossed over with ~50% clearance); small pilot Lyme study (12 participants, 3 g/day for 8 weeks; all reported improvement). Practical details given: typical maintenance dose ~1.5 g/day (two 750 mg capsules), travel/acute-dose strategies of 4–8+ capsules/day were described, and toxicology in animal studies noted no deaths at an estimated 600 g equivalent. Megan emphasizes authenticity/quality issues (many inauthentic or underdosed AHCC products sold online) and points listeners to AHCC research resources and her programs.
